[0003] At present, ship and submarine launching devices use passive control dampers such as rubber pads, disc spring components, oil-gas or oil spring dampers, etc. to reduce vibration. Among them, rubber pads and disc spring components have simple structures and good maintainability, but Poor adaptability to load and excitation; oil-gas or oil spring shock absorbers are usually adjustable, and the flow area is changed by adjusting the opening size of the orifice to adjust the damping coefficient. The required controller and execution The mechanism is complex, and the output damping force changes with the stroke of the piston on the shock absorber. When used in a silo with tight space requirements, it takes up a lot of space

Embodiment Construction
[0028] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Such as Figure 1 to Figure 4 As shown, the disc spring combined magnetorheological damping shock absorber provided by the present invention includes an upper flange 1, a lower flange 2, a magnetorheological damper 3, 8 disc spring assemblies 4, and 3 guide mechanisms 5 And a number of standard parts 6 for connection. The connection mode between the components is as follows: the upper flange 1 and the lower flange 2 are screwed to the other components through the standard part 6 to form a modular shock absorber. Among them, 8 disc spring components 4 are evenly distributed in the circumferential direction between the upper flange 1 and the lower flange 2, forming a circle, and are respectively screwed to the up...

The invention relates to a disc spring-combined magnetorheological damping shock absorber, and relates to the technical field of vibration control for mechanical structures. According to the disc spring-combined magnetorheological damping shock absorber disclosed by the invention, a modularized shock absorber is obtained by combining a magnetorheological damper with a traditional shock absorptioncomponent disc spring in a manner of parallel connection, and realizing vertical shock absorption through a guide mechanism; real-time control for the shock absorber can be realized through a semi-active control method; and adjustable rigidity and damping are realized by changing a current and then changing the magnetic field intensity, and changing the viscidity of a controllable fluid in milliseconds, so that intelligent shock absorption is realized.
Description
technical field [0001] The invention relates to the technical field of mechanical structure vibration control, in particular to a disc spring combined magnetorheological damping shock absorber. Background technique [0002] Reducing the vibration of the aircraft launcher to protect the aircraft and realize the safe launch of the aircraft is a problem that must be considered in the design of the aircraft launcher. Excessive vibration may cause damage to the structure of the launching device, affecting the storage environment of the aircraft and destroying the structural integrity of the aircraft, or the aircraft cannot be launched normally, which will inevitably affect the combat capability of the ship. Due to the large size of the ship and submarine aircraft launching devices, the mass of the loaded barrel bombs is also large. At the same time, since the co-mounted launching device is loaded with multiple barrel bombs, the mass of the entire launching device will change with...
